Coordination Between Spd Low Voltage Lightning Surge Protector And Other Equipment

(1) Under normal conditions, the continuous working current (Ic) shall not cause any personal safety hazards (indirect contact, etc.) or interfere with other equipment. (It is advisable to select a composite SPD low-voltage lightning surge protector with 0 leakage current, which is safer and has a longer service life).

(2) Under fault conditions, the SPD low-voltage lightning surge protection device needs to be installed with a dedicated SPD low-voltage lightning surge protector backup protector so as not to interfere with other protection devices, such as RCD, fuses and circuit breakers. If the overcurrent protector is activated, the system power supply will be interrupted. (It is advisable to select a composite SPD low-voltage lightning surge protective device with 0 continuous current, which will not cause the previous switch to operate and the power supply will continue uninterrupted).
